Amazon.com description: Product Description: Starting with the basic question of what a desert is, and proceeding through a wide variety of questions about the dry desert climate, desert animals, and the different ways humans use the desert, I Wonder Why the Sahara is Cold at Night is a great introduction to this important environment. The question and answer format gets young readers the information they want―like how rattlesnakes kill their prey―while opening up the opportunity for further discussion. The humorous illustrations, child-friendly text, and open-anywhere format make this series a great choice for reluctant readers.
